SanityChelle Posted March 11, 2015 Report Share Posted March 11, 2015 Do you have a plant to identify? You could try check it again here -> http://www.fnzas.org.nz/?page_id=2379 From my knowledge though, I thought there was only one type of duckweed, and it's happy in both coldwater and tropical.

SanityChelle Posted March 11, 2015 Report Share Posted March 11, 2015 If you knew that they were different species, that would have helped. http://www.nzpcn.org.nz/flora_details.aspx?ID=7585 - Lemna disperma / Lemna minor http://www.nzpcn.org.nz/flora_details.aspx?ID=2022 - Lemna aequinoctialis Quote Link to comment Share on other sites More sharing options...
SanityChelle Posted March 11, 2015 Report Share Posted March 11, 2015 From the looks of things, Lemna aequinoctialis has only been collected from Auckland Zoo, where it probably got carried in, and hasn't been found anywhere else. If you have duckweed, it's probably Lemna disperma / Lemna minor. Quote Link to comment Share on other sites More sharing options...
